Hi, I'm looking for some help with my TV. The TV when powered on quickly powers itself off. I called a repair ($96) tech who said it was in the convergance network and would cost up to $700 to fix. I have really enjoyed the TV and wonder if his diagnosis is correct. Can this work be done any cheaper? If it can't I would offer it up to anyone who needs parts as it is a great TV with screen protector. Any ideas would be greatly appreciated.
